#Radioactive Car Emitting 279 Microsieverts/Hr, Reports Asahi Shinbun

I don't know why Asahi is putting out this lame article right now, as it sure looks like the information was there already back in June.

(What surprised me more about the article was that there were over 6,400 workers at the plant at the time of the earthquake/tsunami on March 11.)

All through the summer, as I wrote in my previous post on another radioactive car, there were rumors of cars inside the 20-kilometer "no-entry zone" being shipped outside the zone without any testing, either to the owners or to the used car dealers who sold the cars inside Japan. There is no standard for radiation for used cars sold inside Japan. Back in those days, people who raised the issue of radioactive cars and trucks out of Fukushima were often branded as "racist" discriminating against people in and from Fukushima in both the alternative media and in the MSM.

This blog already reported on the truck in Iwaki City that was emitting 1 millisieverts/hour (1,000 microsieverts/hour) radiation back in August.

From Asahi Shinbun digital version (12/31/2011):

東京電力福島第一原発の事故当時、原発敷地内に駐車していて高濃度に汚染された東電社員らの車について、東電が適切な管理を怠っていた。なかには、中古車市場に流通したり、近隣住民との間でトラブルを起こしたりしている車も出ている。専門家は「放射線量の高い車は、敷地内で発生したがれきと同様に扱うべきだ」と指摘している。

TEPCO didn't do a proper management of cars belonging to TEPCO employees parked inside Fukushima I Nuclear Power Plant at the time of the accident and heavily contaminated with radiation. Some of the cars have been sold in the used car market, others causing problems with the neighbors where the cars are parked. Experts say "Highly radioactive cars should be treated in the same manner as the debris inside the plant compound".

 東電広報部によると、震災から12日後の3月23日からJヴィレッジ(福島県楢葉町、広野町)で放射線検査と除染を始め、一定レベル以上の放射線量の車は外部に出せなくしたが、それ以前は原発敷地内から検査なしで車を持ち出すことが可能だった。震災時、原発内には東電社員755人と協力企業の従業員5660人がいた。社員らが駐車していた車や事故後に持ち出した車の台数は「把握していない」という。

According to the public relations department at TEPCO, the company started the radiation inspection and decontamination at J-Village (located in Naraha-machi and Hirono-machi in Fukushima Prefecture) starting March 23, 12 days after the earthquake/tsunami. From that date, cars that exceeded a certain standard [which changed over time] weren't allowed outside [the no-entry zone]. However, prior to that date, it was possible to bring the cars out of the nuke plant compound without any inspection. At the time of the earthquake/tsunami, there were 755 TEPCO employees and 5660 employees of affiliated companies. TEPCO didn't keep track of the number of cars that were parked inside the plant compound at that time, or the number of cars that were taken outside the plant after the accident.

 今年6月、東電社員から修理を頼まれたという福島県内の自動車修理業者は、「車のワイパー付近で毎時279マイクロシーベルトを計測したんです。何で、こんな車が原発の外に出るのか」と憤り、測定した際の写真を差し出した。仮に1日12分間浴びた場合、年間被曝(ひばく)量が、国が避難を促す目安の年間20ミリシーベルトを超える値だ。

A garage mechanic in Fukushima Prefecture who says he was asked by a TEPCO employee to repair his car in June this year is angry. "279 microsieverts/hour radiation was measured near the windshield wiper. How can they allow a car like this to get ouside the plant?" he said, and showed [the reporter] a photograph he took when he measured the radiation. If one is exposed to that radiation for 12 minutes every day, the annual cumulative radiation exposure would exceed 20 millisieverts which is a standard that the national government uses to prompt residents to evacuate.

12 minutes every day? Realistically if the car was driven to the workplace (Fuku-I plant) and home (say, J-Village, which sits on the edge of the 20-kilometer radius), it is more like 1 hour per day. Instead of over 20 millisieverts, the worker would get 100 millisieverts in one year just by driving his car.

#Radioactive Car Emitting Over 30 Microsieverts/Hr in Musashino City in Tokyo Was Returned to Fukushima

The owner of the car got it from his friend in July and the car was from (guess where) the 20-kilometer radius "no entry zone" in Fukushima Prefecture.

The 20-kilometer "no-entry zone" was officially off-limit until June and the residents weren't allowed to use their own cars until September. Unofficially, there were "rumors" (i.e. not reported in the media) during the summer that people were hired to go and retrieve vehicles inside the 20-kilometer zone. There were also "rumors" of sudden deaths among people who were doing exactly that. The existence of this car in Musashino City, Tokyo is a proof that these reports may have been true.

The car was found emitting over 30 microsieverts/hour radiation at the front grill and inside the engine room. At the perimeter of the parking lot at 1 meter high, the air radiation was 3 microsieverts/hour. Judging by the way the city crafted the announcement, their survey meter went overscale at 30 microsieverts/hour, and the actual radiation level could be much higher.

It was only on December 21 that a citizen finally alerted the city about this radioactivity on wheels.

From the announcement at the Musashino City website:

中町2丁目の駐車場にあった乗用車について、12月21日(水)に市民から高放射線量の情報提供を受け、市で測定したところ、高放射線量が確認されたため、下記のとおり対応いたしました。

Regarding the automobile in a parking garage in Nakacho 2-chome, we were notified by a resident on December 21 of the high radioactivity. We measured the radiation level and confirmed it to be high. Therefore we did the following in response:

 市は、現地で数値の確認を行い、安全を確保したうえで、武蔵野警察の協力を得て、立ち入り禁止措置を行いました。

We confirmed the radiation, and with the help of the Musashino City Police closed off the area after securing safety.

 その後、都ならびに国の指示をあおぎ、対応が決定するまでの間、車を市役所地下駐車場に移し、周辺の出入りを制限して保管しました。

Then we asked for guidance from the Tokyo Metropolitan government and the national government. While we waited for the answer we moved the car to the underground parking at the City Hall, and kept it there limiting the access.

 市は、内閣府原子力災害対策本部に除染の支援を要請し、車の放射線量が毎時30マイクロシーベルトを超えているため、福島県の警戒区域内に戻すことが適当であると決定いたしました。

We asked for assistance in decontamination from the Nuclear Disaster Response Headquarters of the Prime Minister's Office. Since the radiation from the car exceeded 30 microsieverts/hour, it was decided that it would be appropriate to return the car inside the "no entry zone" in Fukushima Prefecture.

 22日(木)午前に、内閣府と東京電力において、車を福島県に搬送し、除染と放射線量の再測定を実施します。線量が一定の基準を下回らなければ、警戒区域から持ち出し不可となります。

On December 22 morning, the Prime Minister's Office and TEPCO would transport the car to Fukushima Prefecture, and conduct decontamination and radiation measurement. If the radiation would not drop below a certain level, the car would not be able to leave the "no entry zone".

 車の所有者である市内の男性は「7月に知人から譲り受けた」としており、福島第一原発事故前後に警戒区域内で使われていたものであったことが判明しました。

The owner of the car is a city resident who says he received the car from his acquaintance in July. It has been revealed that the car was used inside the "no-entry zone" before and after the Fukushima I Nuclear Power Plant accident.

 車を移動させた後の、近隣区域の放射線量は、市の基準値(毎時0.23マイクロシーベルト)を下回っていることを確認いたしました。

After the car was moved, the radiation levels in the vicinity were confirmed to be below the limit that the city sets (0.23 microsievert/hour).

Radiation levels (from the chart at Musashino City's website, above):

  • Perimeter of the parking lot at 5 centimeters off the ground: 2.60 microsieverts/hour

  • Perimeter of the parking lot at 1 meter off the ground: 3.08 microsieverts/hour

  • Car, front grill: more than 30 microsieverts/hour

  • Car, inside the engine room: more than 30 microsieverts/hour

  • 7 meters from the car in both north and south directions at 1 meter off the ground: 0.19 to 0.23 microsievert/hour

After the car was removed, the radiation levels on the parking lot dropped to 0.11 microsievert/hour, post-Fukushima normal, so to speak.

It looks like there is a kindergarten within 3 minutes of walk from this particular parking lot, which costs about US$320 a month to rent a parking space. This car has been in this parking lot, and running around in town and maybe beyond, for 6 months. It would have continued to do so without the report from a citizen armed with his/her survey meter.
